Delegation problem ??

[Raphaël Berghmans]

Hi,

We've got a domain : irisnet.be, and we delegate a sub-domain : arp.irisnet.be.

The parent and the child are properly configured, but the parent send very often to his child a request. The output of tcpdump :

11:00:24.007336 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 29049 (32)
11:01:36.007342 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 9183 (32)
11:03:47.007362 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 33079 (38)
11:04:45.007327 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 30180 (32)
11:05:23.007349 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 56829 (39)
11:07:01.007326 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 1794 (31)
11:11:27.007336 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 52533 (38)
11:13:14.007327 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 32005 (32)
11:14:51.007326 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 39799 (32)
11:14:54.007327 ns.irisnet.be.domain > dns.arp.irisnet.be.domain: 40832 (39)

Could you please tell why ?

Thank you,

Raphaël
